Supco SHL524 Limit Switch L170-20F

The Supco SHL524 Limit Switch performs as an automatic thermal monitoring component that responds when surrounding conditions exceed its calibrated setting. It opens the circuit at 170F and automatically restores electrical continuity after the limit drops by 20F preventing the need for manual resetting. It is mounted at the designated sensing position to continuously monitor operating temperatures. Its automatic action reduces excessive heat exposure in HVAC systems supports dependable thermal monitoring, improves operational safety, minimizes unnecessary interruptions, maintains proper temperature response, and encourages stable operating conditions through automatic reset capability.
